" Version 3, 29 June 2007\n" +
"\n" +
"Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>\n" +
"Everyone is permitted to copy and distribute verbatim copies\n" +
"of this license document, but changing it is not allowed.\n" +
"\n" +
" Preamble\n" +
"\n" +
"The GNU General Public License is a free, copyleft license for\n" +
"software and other kinds of works.\n" +
"\n" +
"The licenses for most software and other practical works are designed\n" +
"to take away your freedom to share and change the works. By contrast,\n" +
"the GNU General Public License is intended to guarantee your freedom to\n" +
"share and change all versions of a program--to make sure it remains free\n" +
"software for all its users. We, the Free Software Foundation, use the\n" +
"GNU General Public License for most of our software; it applies also to\n" +
"any other work released this way by its authors. You can apply it to\n" +
"your programs, too.\n" +
"\n" +
"When we speak of free software, we are referring to freedom, not\n" +
"price. Our General Public Licenses are designed to make sure that you\n" +
"have the freedom to distribute copies of free software (and charge for\n" +
"them if you wish), that you receive source code or can get it if you\n" +
"want it, that you can change the software or use pieces of it in new\n" +
"free programs, and that you know you can do these things.\n" +
"\n" +
"To protect your rights, we need to prevent others from denying you\n" +
"these rights or asking you to surrender the rights. Therefore, you have\n" +
"certain responsibilities if you distribute copies of the software, or if\n" +
"you modify it: responsibilities to respect the freedom of others.\n" +
"\n" +
"For example, if you distribute copies of such a program, whether\n" +
"gratis or for a fee, you must pass on to the recipients the same\n" +
"freedoms that you received. You must make sure that they, too, receive\n" +
"or can get the source code. And you must show them these terms so they\n" +
"know their rights.\n" +
"\n" +
"Developers that use the GNU GPL protect your rights with two steps:\n" +
"(1) assert copyright on the software, and (2) offer you this License\n" +
"giving you legal permission to copy, distribute and/or modify it.\n" +
"\n" +
"For the developers' and authors' protection, the GPL clearly explains\n" +
"that there is no warranty for this free software. For both users' and\n" +
"authors' sake, the GPL requires that modified versions be marked as\n" +
"changed, so that their problems will not be attributed erroneously to\n" +
"authors of previous versions.\n" +
"\n" +
"Some devices are designed to deny users access to install or run\n" +
"modified versions of the software inside them, although the manufacturer\n" +
"can do so. This is fundamentally incompatible with the aim of\n" +
"protecting users' freedom to change the software. The systematic\n" +
"pattern of such abuse occurs in the area of products for individuals to\n" +
"use, which is precisely where it is most unacceptable. Therefore, we\n" +
"have designed this version of the GPL to prohibit the practice for those\n" +
"products. If such problems arise substantially in other domains, we\n" +
"stand ready to extend this provision to those domains in future versions\n" +
"of the GPL, as needed to protect the freedom of users.\n" +
"\n" +
"Finally, every program is threatened constantly by software patents.\n" +
"States should not allow patents to restrict development and use of\n" +
"software on general-purpose computers, but in those that do, we wish to\n" +
"avoid the special danger that patents applied to a free program could\n" +
"make it effectively proprietary. To prevent this, the GPL assures that\n" +
"patents cannot be used to render the program non-free.\n" +
"\n" +
"The precise terms and conditions for copying, distribution and\n" +
"modification follow.\n" +
"\n" +
" TERMS AND CONDITIONS\n" +
"\n" +
"0. Definitions.\n" +
"\n" +
"\"This License\" refers to version 3 of the GNU General Public License.\n" +
"\n" +
"\"Copyright\" also means copyright-like laws that apply to other kinds of\n" +
"works, such as semiconductor masks.\n" +
"\n" +
"\"The Program\" refers to any copyrightable work licensed under this\n" +
"License. Each licensee is addressed as \"you\". \"Licensees\" and\n" +
"\"recipients\" may be individuals or organizations.\n" +
"\n" +
"To \"modify\" a work means to copy from or adapt all or part of the work\n" +
"in a fashion requiring copyright permission, other than the making of an\n" +
"exact copy. The resulting work is called a \"modified version\" of the\n" +
"earlier work or a work \"based on\" the earlier work.\n" +
"\n" +
"A \"covered work\" means either the unmodified Program or a work based\n" +
"on the Program.\n" +
"\n" +
"To \"propagate\" a work means to do anything with it that, without\n" +
"permission, would make you directly or secondarily liable for\n" +
"infringement under applicable copyright law, except executing it on a\n" +
"computer or modifying a private copy. Propagation includes copying,\n" +
"distribution (with or without modification), making available to the\n" +
"public, and in some countries other activities as well.\n" +
"\n" +
"To \"convey\" a work means any kind of propagation that enables other\n" +
"parties to make or receive copies. Mere interaction with a user through\n" +
"a computer network, with no transfer of a copy, is not conveying.\n" +
"\n" +
"An interactive user interface displays \"Appropriate Legal Notices\"\n" +
"to the extent that it includes a convenient and prominently visible\n" +
"feature that (1) displays an appropriate copyright notice, and (2)\n" +
"tells the user that there is no warranty for the work (except to the\n" +
"extent that warranties are provided), that licensees may convey the\n" +
"work under this License, and how to view a copy of this License. If\n" +
"the interface presents a list of user commands or options, such as a\n" +
"menu, a prominent item in the list meets this criterion.\n" +
"\n" +
"1. Source Code.\n" +
"\n" +
"The \"source code\" for a work means the preferred form of the work\n" +
"for making modifications to it. \"Object code\" means any non-source\n" +
"form of a work.\n" +
"\n" +
"A \"Standard Interface\" means an interface that either is an official\n" +
"standard defined by a recognized standards body, or, in the case of\n" +
"interfaces specified for a particular programming language, one that\n" +
"is widely used among developers working in that language.\n" +
"\n" +
"The \"System Libraries\" of an executable work include anything, other\n" +
"than the work as a whole, that (a) is included in the normal form of\n" +
"packaging a Major Component, but which is not part of that Major\n" +
"Component, and (b) serves only to enable use of the work with that\n" +
"Major Component, or to implement a Standard Interface for which an\n" +
"implementation is available to the public in source code form. A\n" +
"\"Major Component\", in this context, means a major essential component\n" +
"(kernel, window system, and so on) of the specific operating system\n" +
"(if any) on which the executable work runs, or a compiler used to\n" +
"produce the work, or an object code interpreter used to run it.\n" +
"\n" +
"The \"Corresponding Source\" for a work in object code form means all\n" +
"the source code needed to generate, install, and (for an executable\n" +
"work) run the object code and to modify the work, including scripts to\n" +
"control those activities. However, it does not include the work's\n" +
"System Libraries, or general-purpose tools or generally available free\n" +
"programs which are used unmodified in performing those activities but\n" +
"which are not part of the work. For example, Corresponding Source\n" +
"includes interface definition files associated with source files for\n" +
"the work, and the source code for shared libraries and dynamically\n" +
"linked subprograms that the work is specifically designed to require,\n" +
"such as by intimate data communication or control flow between those\n" +
"subprograms and other parts of the work.\n" +
"\n" +
"The Corresponding Source need not include anything that users\n" +
"can regenerate automatically from other parts of the Corresponding\n" +
"Source.\n" +
"\n" +
"The Corresponding Source for a work in source code form is that\n" +
"same work.\n" +
"\n" +
"2. Basic Permissions.\n" +
"\n" +
"All rights granted under this License are granted for the term of\n" +
"copyright on the Program, and are irrevocable provided the stated\n" +
"conditions are met. This License explicitly affirms your unlimited\n" +
"permission to run the unmodified Program. The output from running a\n" +
"covered work is covered by this License only if the output, given its\n" +
"content, constitutes a covered work. This License acknowledges your\n" +
"rights of fair use or other equivalent, as provided by copyright law.\n" +
"\n" +
"You may make, run and propagate covered works that you do not\n" +
"convey, without conditions so long as your license otherwise remains\n" +
"in force. You may convey covered works to others for the sole purpose\n" +
"of having them make modifications exclusively for you, or provide you\n" +
"with facilities for running those works, provided that you comply with\n" +
"the terms of this License in conveying all material for which you do\n" +
"not control copyright. Those thus making or running the covered works\n" +
"for you must do so exclusively on your behalf, under your direction\n" +
"and control, on terms that prohibit them from making any copies of\n" +
"your copyrighted material outside their relationship with you.\n" +
"\n" +
"Conveying under any other circumstances is permitted solely under\n" +
"the conditions stated below. Sublicensing is not allowed; section 10\n" +
"makes it unnecessary.\n" +
"\n" +
"3. Protecting Users' Legal Rights From Anti-Circumvention Law.\n" +
"\n" +
"No covered work shall be deemed part of an effective technological\n" +
"measure under any applicable law fulfilling obligations under article\n" +
"11 of the WIPO copyright treaty adopted on 20 December 1996, or\n" +
"similar laws prohibiting or restricting circumvention of such\n" +
"measures.\n" +
"\n" +
"When you convey a covered work, you waive any legal power to forbid\n" +
"circumvention of technological measures to the extent such circumvention\n" +
"is effected by exercising rights under this License with respect to\n" +
"the covered work, and you disclaim any intention to limit operation or\n" +
"modification of the work as a means of enforcing, against the work's\n" +
"users, your or third parties' legal rights to forbid circumvention of\n" +
"technological measures.\n" +
"\n" +
"4. Conveying Verbatim Copies.\n" +
"\n" +
"You may convey verbatim copies of the Program's source code as you\n" +
"receive it, in any medium, provided that you conspicuously and\n" +
"appropriately publish on each copy an appropriate copyright notice;\n" +
"keep intact all notices stating that this License and any\n" +
"non-permissive terms added in accord with section 7 apply to the code;\n" +
"keep intact all notices of the absence of any warranty; and give all\n" +
"recipients a copy of this License along with the Program.\n" +
"\n" +
"You may charge any price or no price for each copy that you convey,\n" +
"and you may offer support or warranty protection for a fee.\n" +
"\n" +
"5. Conveying Modified Source Versions.\n" +
"\n" +
"You may convey a work based on the Program, or the modifications to\n" +
"produce it from the Program, in the form of source code under the\n" +
"terms of section 4, provided that you also meet all of these conditions:\n" +
"\n" +
"a) The work must carry prominent notices stating that you modified\n" +
"it, and giving a relevant date.\n" +
"\n" +
"b) The work must carry prominent notices stating that it is\n" +
"released under this License and any conditions added under section\n" +
"7. This requirement modifies the requirement in section 4 to\n" +
"\"keep intact all notices\".\n" +
"\n" +
"c) You must license the entire work, as a whole, under this\n" +
"License to anyone who comes into possession of a copy. This\n" +
"License will therefore apply, along with any applicable section 7\n" +
"additional terms, to the whole of the work, and all its parts,\n" +
"regardless of how they are packaged. This License gives no\n" +
"permission to license the work in any other way, but it does not\n" +
"invalidate such permission if you have separately received it.\n" +
"\n" +
"d) If the work has interactive user interfaces, each must display\n" +
"Appropriate Legal Notices; however, if the Program has interactive\n" +
"interfaces that do not display Appropriate Legal Notices, your\n" +
"work need not make them do so.\n" +
"\n" +
"A compilation of a covered work with other separate and independent\n" +
"works, which are not by their nature extensions of the covered work,\n" +
"and which are not combined with it such as to form a larger program,\n" +
"in or on a volume of a storage or distribution medium, is called an\n" +
"\"aggregate\" if the compilation and its resulting copyright are not\n" +
"used to limit the access or legal rights of the compilation's users\n" +
"beyond what the individual works permit. Inclusion of a covered work\n" +
"in an aggregate does not cause this License to apply to the other\n" +
"parts of the aggregate.\n" +
"\n" +
"6. Conveying Non-Source Forms.\n" +
"\n" +
"You may convey a covered work in object code form under the terms\n" +
"of sections 4 and 5, provided that you also convey the\n" +
"machine-readable Corresponding Source under the terms of this License,\n" +
"in one of these ways:\n" +
"\n" +
"a) Convey the object code in, or embodied in, a physical product\n" +
"(including a physical distribution medium), accompanied by the\n" +
"Corresponding Source fixed on a durable physical medium\n" +
"customarily used for software interchange.\n" +
"\n" +
"b) Convey the object code in, or embodied in, a physical product\n" +
"(including a physical distribution medium), accompanied by a\n" +
"written offer, valid for at least three years and valid for as\n" +
"long as you offer spare parts or customer support for that product\n" +
"model, to give anyone who possesses the object code either (1) a\n" +
"copy of the Corresponding Source for all the software in the\n" +
"product that is covered by this License, on a durable physical\n" +
"medium customarily used for software interchange, for a price no\n" +
"more than your reasonable cost of physically performing this\n" +
"conveying of source, or (2) access to copy the\n" +
"Corresponding Source from a network server at no charge.\n" +
"\n" +
"c) Convey individual copies of the object code with a copy of the\n" +
"written offer to provide the Corresponding Source. This\n" +
"alternative is allowed only occasionally and noncommercially, and\n" +
"only if you received the object code with such an offer, in accord\n" +
"with subsection 6b.\n" +
"\n" +
"d) Convey the object code by offering access from a designated\n" +
"place (gratis or for a charge), and offer equivalent access to the\n" +
"Corresponding Source in the same way through the same place at no\n" +
"further charge. You need not require recipients to copy the\n" +
"Corresponding Source along with the object code. If the place to\n" +
"copy the object code is a network server, the Corresponding Source\n" +
"may be on a different server (operated by you or a third party)\n" +
"that supports equivalent copying facilities, provided you maintain\n" +
"clear directions next to the object code saying where to find the\n" +
"Corresponding Source. Regardless of what server hosts the\n" +
"Corresponding Source, you remain obligated to ensure that it is\n" +
"available for as long as needed to satisfy these requirements.\n" +
"\n" +
"e) Convey the object code using peer-to-peer transmission, provided\n" +
"you inform other peers where the object code and Corresponding\n" +
"Source of the work are being offered to the general public at no\n" +
"charge under subsection 6d.\n" +
"\n" +
"A separable portion of the object code, whose source code is excluded\n" +
"from the Corresponding Source as a System Library, need not be\n" +
"included in conveying the object code work.\n" +
"\n" +
"A \"User Product\" is either (1) a \"consumer product\", which means any\n" +
"tangible personal property which is normally used for personal, family,\n" +
"or household purposes, or (2) anything designed or sold for incorporation\n" +
"into a dwelling. In determining whether a product is a consumer product,\n" +
"doubtful cases shall be resolved in favor of coverage. For a particular\n" +
"product received by a particular user, \"normally used\" refers to a\n" +
"typical or common use of that class of product, regardless of the status\n" +
"of the particular user or of the way in which the particular user\n" +
"actually uses, or expects or is expected to use, the product. A product\n" +
"is a consumer product regardless of whether the product has substantial\n" +
"commercial, industrial or non-consumer uses, unless such uses represent\n" +
"the only significant mode of use of the product.\n" +
"\n" +
"\"Installation Information\" for a User Product means any methods,\n" +
"procedures, authorization keys, or other information required to install\n" +
"and execute modified versions of a covered work in that User Product from\n" +
"a modified version of its Corresponding Source. The information must\n" +
"suffice to ensure that the continued functioning of the modified object\n" +
"code is in no case prevented or interfered with solely because\n" +
"modification has been made.\n" +
"\n" +
"If you convey an object code work under this section in, or with, or\n" +
"specifically for use in, a User Product, and the conveying occurs as\n" +
"part of a transaction in which the right of possession and use of the\n" +
"User Product is transferred to the recipient in perpetuity or for a\n" +
"fixed term (regardless of how the transaction is characterized), the\n" +
"Corresponding Source conveyed under this section must be accompanied\n" +
"by the Installation Information. But this requirement does not apply\n" +
"if neither you nor any third party retains the ability to install\n" +
"modified object code on the User Product (for example, the work has\n" +
"been installed in ROM).\n" +
"\n" +
"The requirement to provide Installation Information does not include a\n" +
"requirement to continue to provide support service, warranty, or updates\n" +
"for a work that has been modified or installed by the recipient, or for\n" +
"the User Product in which it has been modified or installed. Access to a\n" +
"network may be denied when the modification itself materially and\n" +
"adversely affects the operation of the network or violates the rules and\n" +
"protocols for communication across the network.\n" +
"\n" +
"Corresponding Source conveyed, and Installation Information provided,\n" +
"in accord with this section must be in a format that is publicly\n" +
"documented (and with an implementation available to the public in\n" +
"source code form), and must require no special password or key for\n" +
"unpacking, reading or copying.\n" +
"\n" +
"7. Additional Terms.\n" +
"\n" +
"\"Additional permissions\" are terms that supplement the terms of this\n" +
"License by making exceptions from one or more of its conditions.\n" +
"Additional permissions that are applicable to the entire Program shall\n" +
"be treated as though they were included in this License, to the extent\n" +
"that they are valid under applicable law. If additional permissions\n" +
"apply only to part of the Program, that part may be used separately\n" +
"under those permissions, but the entire Program remains governed by\n" +
"this License without regard to the additional permissions.\n" +
"\n" +
"When you convey a copy of a covered work, you may at your option\n" +
"remove any additional permissions from that copy, or from any part of\n" +
"it. (Additional permissions may be written to require their own\n" +
"removal in certain cases when you modify the work.) You may place\n" +
"additional permissions on material, added by you to a covered work,\n" +
"for which you have or can give appropriate copyright permission.\n" +
"\n" +
"Notwithstanding any other provision of this License, for material you\n" +
"add to a covered work, you may (if authorized by the copyright holders of\n" +
"that material) supplement the terms of this License with terms:\n" +
"\n" +
"a) Disclaiming warranty or limiting liability differently from the\n" +
"terms of sections 15 and 16 of this License; or\n" +
"\n" +
"b) Requiring preservation of specified reasonable legal notices or\n" +
"author attributions in that material or in the Appropriate Legal\n" +
"Notices displayed by works containing it; or\n" +
"\n" +
"c) Prohibiting misrepresentation of the origin of that material, or\n" +
"requiring that modified versions of such material be marked in\n" +
"reasonable ways as different from the original version; or\n" +
"\n" +
"d) Limiting the use for publicity purposes of names of licensors or\n" +
"authors of the material; or\n" +
"\n" +
"e) Declining to grant rights under trademark law for use of some\n" +
"trade names, trademarks, or service marks; or\n" +
"\n" +
"f) Requiring indemnification of licensors and authors of that\n" +
"material by anyone who conveys the material (or modified versions of\n" +
"it) with contractual assumptions of liability to the recipient, for\n" +
"any liability that these contractual assumptions directly impose on\n" +
"those licensors and authors.\n" +
"\n" +
"All other non-permissive additional terms are considered \"further\n" +
"restrictions\" within the meaning of section 10. If the Program as you\n" +
"received it, or any part of it, contains a notice stating that it is\n" +
"governed by this License along with a term that is a further\n" +
"restriction, you may remove that term. If a license document contains\n" +
"a further restriction but permits relicensing or conveying under this\n" +
"License, you may add to a covered work material governed by the terms\n" +
"of that license document, provided that the further restriction does\n" +
"not survive such relicensing or conveying.\n" +
"\n" +
"If you add terms to a covered work in accord with this section, you\n" +
"must place, in the relevant source files, a statement of the\n" +
"additional terms that apply to those files, or a notice indicating\n" +
"where to find the applicable terms.\n" +
"\n" +
"Additional terms, permissive or non-permissive, may be stated in the\n" +
"form of a separately written license, or stated as exceptions;\n" +
"the above requirements apply either way.\n" +
"\n" +
"8. Termination.\n" +
"\n" +
"You may not propagate or modify a covered work except as expressly\n" +
"provided under this License. Any attempt otherwise to propagate or\n" +
"modify it is void, and will automatically terminate your rights under\n" +
"this License (including any patent licenses granted under the third\n" +
"paragraph of section 11).\n" +
"\n" +
"However, if you cease all violation of this License, then your\n" +
"license from a particular copyright holder is reinstated (a)\n" +
"provisionally, unless and until the copyright holder explicitly and\n" +
"finally terminates your license, and (b) permanently, if the copyright\n" +
"holder fails to notify you of the violation by some reasonable means\n" +
"prior to 60 days after the cessation.\n" +
"\n" +
"Moreover, your license from a particular copyright holder is\n" +
"reinstated permanently if the copyright holder notifies you of the\n" +
"violation by some reasonable means, this is the first time you have\n" +
"received notice of violation of this License (for any work) from that\n" +
"copyright holder, and you cure the violation prior to 30 days after\n" +
"your receipt of the notice.\n" +
"\n" +
"Termination of your rights under this section does not terminate the\n" +
"licenses of parties who have received copies or rights from you under\n" +
"this License. If your rights have been terminated and not permanently\n" +
"reinstated, you do not qualify to receive new licenses for the same\n" +
"material under section 10.\n" +
"\n" +
"9. Acceptance Not Required for Having Copies.\n" +
"\n" +
"You are not required to accept this License in order to receive or\n" +
"run a copy of the Program. Ancillary propagation of a covered work\n" +
"occurring solely as a consequence of using peer-to-peer transmission\n" +
"to receive a copy likewise does not require acceptance. However,\n" +
"nothing other than this License grants you permission to propagate or\n" +
"modify any covered work. These actions infringe copyright if you do\n" +
"not accept this License. Therefore, by modifying or propagating a\n" +
"covered work, you indicate your acceptance of this License to do so.\n" +
"\n" +
"10. Automatic Licensing of Downstream Recipients.\n" +
"\n" +
"Each time you convey a covered work, the recipient automatically\n" +
"receives a license from the original licensors, to run, modify and\n" +
"propagate that work, subject to this License. You are not responsible\n" +
"for enforcing compliance by third parties with this License.\n" +
"\n" +
"An \"entity transaction\" is a transaction transferring control of an\n" +
"organization, or substantially all assets of one, or subdividing an\n" +
"organization, or merging organizations. If propagation of a covered\n" +
"work results from an entity transaction, each party to that\n" +
"transaction who receives a copy of the work also receives whatever\n" +
"licenses to the work the party's predecessor in interest had or could\n" +
"give under the previous paragraph, plus a right to possession of the\n" +
"Corresponding Source of the work from the predecessor in interest, if\n" +
"the predecessor has it or can get it with reasonable efforts.\n" +
"\n" +
"You may not impose any further restrictions on the exercise of the\n" +
"rights granted or affirmed under this License. For example, you may\n" +
"not impose a license fee, royalty, or other charge for exercise of\n" +
"rights granted under this License, and you may not initiate litigation\n" +
"(including a cross-claim or counterclaim in a lawsuit) alleging that\n" +
"any patent claim is infringed by making, using, selling, offering for\n" +
"sale, or importing the Program or any portion of it.\n" +
"\n" +
"11. Patents.\n" +
"\n" +
"A \"contributor\" is a copyright holder who authorizes use under this\n" +
"License of the Program or a work on which the Program is based. The\n" +
"work thus licensed is called the contributor's \"contributor version\".\n" +
"\n" +
"A contributor's \"essential patent claims\" are all patent claims\n" +
"owned or controlled by the contributor, whether already acquired or\n" +
"hereafter acquired, that would be infringed by some manner, permitted\n" +
"by this License, of making, using, or selling its contributor version,\n" +
"but do not include claims that would be infringed only as a\n" +
"consequence of further modification of the contributor version. For\n" +
"purposes of this definition, \"control\" includes the right to grant\n" +
"patent sublicenses in a manner consistent with the requirements of\n" +
"this License.\n" +
"\n" +
"Each contributor grants you a non-exclusive, worldwide, royalty-free\n" +
"patent license under the contributor's essential patent claims, to\n" +
"make, use, sell, offer for sale, import and otherwise run, modify and\n" +
"propagate the contents of its contributor version.\n" +
"\n" +
"In the following three paragraphs, a \"patent license\" is any express\n" +
"agreement or commitment, however denominated, not to enforce a patent\n" +
"(such as an express permission to practice a patent or covenant not to\n" +
"sue for patent infringement). To \"grant\" such a patent license to a\n" +
"party means to make such an agreement or commitment not to enforce a\n" +
"patent against the party.\n" +
"\n" +
"If you convey a covered work, knowingly relying on a patent license,\n" +
"and the Corresponding Source of the work is not available for anyone\n" +
"to copy, free of charge and under the terms of this License, through a\n" +
"publicly available network server or other readily accessible means,\n" +
"then you must either (1) cause the Corresponding Source to be so\n" +
"available, or (2) arrange to deprive yourself of the benefit of the\n" +
"patent license for this particular work, or (3) arrange, in a manner\n" +
"consistent with the requirements of this License, to extend the patent\n" +
"license to downstream recipients. \"Knowingly relying\" means you have\n" +
"actual knowledge that, but for the patent license, your conveying the\n" +
"covered work in a country, or your recipient's use of the covered work\n" +
"in a country, would infringe one or more identifiable patents in that\n" +
"country that you have reason to believe are valid.\n" +
"\n" +
"If, pursuant to or in connection with a single transaction or\n" +
"arrangement, you convey, or propagate by procuring conveyance of, a\n" +
"covered work, and grant a patent license to some of the parties\n" +
"receiving the covered work authorizing them to use, propagate, modify\n" +
"or convey a specific copy of the covered work, then the patent license\n" +
"you grant is automatically extended to all recipients of the covered\n" +
"work and works based on it.\n" +
"\n" +
"A patent license is \"discriminatory\" if it does not include within\n" +
"the scope of its coverage, prohibits the exercise of, or is\n" +
"conditioned on the non-exercise of one or more of the rights that are\n" +
"specifically granted under this License. You may not convey a covered\n" +
"work if you are a party to an arrangement with a third party that is\n" +
"in the business of distributing software, under which you make payment\n" +
"to the third party based on the extent of your activity of conveying\n" +
"the work, and under which the third party grants, to any of the\n" +
"parties who would receive the covered work from you, a discriminatory\n" +
"patent license (a) in connection with copies of the covered work\n" +
"conveyed by you (or copies made from those copies), or (b) primarily\n" +
"for and in connection with specific products or compilations that\n" +
"contain the covered work, unless you entered into that arrangement,\n" +
"or that patent license was granted, prior to 28 March 2007.\n" +
"\n" +
"Nothing in this License shall be construed as excluding or limiting\n" +
"any implied license or other defenses to infringement that may\n" +
"otherwise be available to you under applicable patent law.\n" +
"\n" +
"12. No Surrender of Others' Freedom.\n" +
"\n" +
"If conditions are imposed on you (whether by court order, agreement or\n" +
"otherwise) that contradict the conditions of this License, they do not\n" +
"excuse you from the conditions of this License. If you cannot convey a\n" +
"covered work so as to satisfy simultaneously your obligations under this\n" +
"License and any other pertinent obligations, then as a consequence you may\n" +
"not convey it at all. For example, if you agree to terms that obligate you\n" +
"to collect a royalty for further conveying from those to whom you convey\n" +
"the Program, the only way you could satisfy both those terms and this\n" +
"License would be to refrain entirely from conveying the Program.\n" +
"\n" +
"13. Use with the GNU Affero General Public License.\n" +
"\n" +
"Notwithstanding any other provision of this License, you have\n" +
"permission to link or combine any covered work with a work licensed\n" +
"under version 3 of the GNU Affero General Public License into a single\n" +
"combined work, and to convey the resulting work. The terms of this\n" +
"License will continue to apply to the part which is the covered work,\n" +
"but the special requirements of the GNU Affero General Public License,\n" +
"section 13, concerning interaction through a network will apply to the\n" +
"combination as such.\n" +
"\n" +
"14. Revised Versions of this License.\n" +
"\n" +
"The Free Software Foundation may publish revised and/or new versions of\n" +
"the GNU General Public License from time to time. Such new versions will\n" +
"be similar in spirit to the present version, but may differ in detail to\n" +
"address new problems or concerns.\n" +
"\n" +
"Each version is given a distinguishing version number. If the\n" +
"Program specifies that a certain numbered version of the GNU General\n" +
"Public License \"or any later version\" applies to it, you have the\n" +
"option of following the terms and conditions either of that numbered\n" +
"version or of any later version published by the Free Software\n" +
"Foundation. If the Program does not specify a version number of the\n" +
"GNU General Public License, you may choose any version ever published\n" +
"by the Free Software Foundation.\n" +
"\n" +
"If the Program specifies that a proxy can decide which future\n" +
"versions of the GNU General Public License can be used, that proxy's\n" +
"public statement of acceptance of a version permanently authorizes you\n" +
"to choose that version for the Program.\n" +
"\n" +
"Later license versions may give you additional or different\n" +
"permissions. However, no additional obligations are imposed on any\n" +
"author or copyright holder as a result of your choosing to follow a\n" +
"later version.\n" +
"\n" +
"15. Disclaimer of Warranty.\n" +
"\n" +
"THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY\n" +
"APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT\n" +
"HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM \"AS IS\" WITHOUT WARRANTY\n" +
"OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,\n" +
"THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR\n" +
"PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM\n" +
"IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF\n" +
"ALL NECESSARY SERVICING, REPAIR OR CORRECTION.\n" +
"\n" +
"16. Limitation of Liability.\n" +
"\n" +
"IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\n" +
"WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS\n" +
"THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY\n" +
"GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE\n" +
"USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF\n" +
"DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD\n" +
"PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),\n" +
"EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF\n" +
"SUCH DAMAGES.\n" +
"\n" +
"17. Interpretation of Sections 15 and 16.\n" +
"\n" +
"If the disclaimer of warranty and limitation of liability provided\n" +
"above cannot be given local legal effect according to their terms,\n" +
"reviewing courts shall apply local law that most closely approximates\n" +
"an absolute waiver of all civil liability in connection with the\n" +
"Program, unless a warranty or assumption of liability accompanies a\n" +
"copy of the Program in return for a fee.\n" +
"\n" +
" END OF TERMS AND CONDITIONS");
